CAN-HEADINQG MACHINE.

SPECIFICATION forming part of Letters Fatent No. 525,100, dated August28, 1894. Application filed Janua y 4, 189.4. Serial No. 495,610. (Nomodel.)

To all whom it may concern.-

Be it known that I, JAMES GOULD, J r., a

. citizen of the United States, residing in San Francisco, in the countyof San Francisco and State of California, have-invented a new and usefulImprovement in Can -Heading Machines,of which the following is aspecification.

My invention relates to can heading machines.

The object of my invention is to provide a machine of a simple andefficient construction for automatically applying tight exteriorlyfitting can heads to can bodies of a particular kind, wherein the canbodies are made'of two diameters dilfering by the thickness of the tinin the can head flange the smaller diameter of the can bodycorresponding in size to the interior diameter of the can head flangeand the larger diameter of the can body to the exterior diameter of thecan head flange.

My invention consists in the novel devices and novel combinations ofparts and devices herein shown and described and more particularlypointed out in the claims.

In the accompanying drawings which form a part of this specification,and in which similar letters of reference indicate like parts throughoutall the figures, Figure 1 is a' plan View of a machine embodying myinvention. Figs. 2 and; are vertical cross sections taken on the line2-2 of Fig. 1, and looking in opposite directions the parts being shownhowever in different relative positions in the two figures. Fig. 3 is apartial vertical section taken on the line 3-3 of Fig.1. Fig. 5 is adetail view showing in elevation the can head feed chute and the devicefor regulating the feed of the canheads in the chute, and Fig. 6 showsthe particular construction of can for the heading of which the machineis designed.

In thedrawings' A represents the frame of the machine.

B B are a pair of reciprocating header rings.

headers or rings B B. Each of these headers or rings B B has an interiordiameter 1) corresponding to the exterior diameter of the larger portiona: of the can body and to the exterior-diameter of the can head. Each ofthese headers B is also furnished with a bev-, eled or flaring mouth I)to adapt the can bodies to enter the same 'endwise. Each of thesereciprocating headers or rings B B is also furnished with a lateral slotor opening b through the same for the admission of the can heads.

0 G are a pair of reciprocating plates or plungers mounted in the hollowheader rings BB, the purpose of which is, after the heads have beenapplied to the can, to prevent any tendency of the headers by theirbackward movement to draw off or loosen the heads from the can. Theseplates, pistonsorplungers O C are heldin their forward position so as topress or hold the headed can between them by means of pawls or catchesD, D, one on each side, pivoted to the frame at d and engaging aprojection c on the stem 0 of the piston or plate 0. A spring at servesto hold the pawl D in place. This pawl D is withdrawn as the header Bcompletes its backward movement by means of a cam or projection bthereon which strikes against the end of the pawl D and thus throws itdown so as to release the projection c from engagement with the pawl. Aspring 0'? interposed between the header B and the projection c thenwithdraws the piston C.

. E represents a continuously moving can body carrier,'the same beingpreferably a flexible or chain carrier furnished with suitable fingersor pockets E for supporting the can body and conveying the same to aposition between the reciprocating headers B B. This carrier receivesmotion from a sprocket wheel E secured to a shaft E connected bysuitable gearing with the main driving shaft of the machine. Just as thecan body is conveyed to a position between the headers B B by thecontinuously moving carrier E the headers B B move forward or towardeach other, and slipping over the ends of the can body size and round itby contact of its cylindrical surface I) with the cylindrical surface ofthe larger diameter a; of the can body so as to adapt its smallerdiameter to enter accurately within the flange of the can head as theheaders B B are forced together or toward each other. After the can bodyis begun to be grasped by the headers or begins to enter the beveled orflaring mouths bl/ of the headers, the forward motion of the can body isof course arrested by the headers, and the can body carrier continuingits movement leaves the can body behind.

The space between the fingers or pockets E E of the carrier E issufiicient to give time for the headers B B to move forward, head thecan and again retreat before the succeeding pocket or finger reaches theheading position. As each can body is in turn brought into positionbetween the headers B B, the headers move forward and grasp it, head thecan and again retreat while the finger E on the continually movingcarrier leaves the can behind. After the can is headed and the headers BB retreat or withdraw the headed can drops and may fall either entirelyout of the machine or into a suitable discharge chute, or in falling itmay again overtake the finger E, which carried it into position, and beby it conveyed out of the machine or into a discharge chute.

F F are a pair of can head feed chutes or passages along which the canheads move or travel. These chutes are stationary, being attached to thestationary frame of the machine. When the headers B B are in theirretracted position the lateral slots b b are brought into registry withthe can head feed chutes or passages, so that the lowermost can head ineach chute may drop or move into the header ring or device. At this timethe springs 0 have also retracted the pistons or plungers C C. Toregulate the feed of the can head chutes, a vibrating lever or trigger Gis provided in each of the can head chutes. Each of these triggers G ispivoted at g to the frame or can head chute and is furnished with twopins or projections g 9 located at least the diameter of a can headapart, so that when the lever or trigger is vibrated to withdraw thelowermost pin g out of the way to permit the lowermost can head to pass,the uppermost pin 9 will be thrust inward in the path of the nextsucceeding can head to prevent its downward movement until the lever ortrigger again vibrates into its normal position wherein the lowermostpin b projects across the path of the can head in the chute. A spring gholds the lever or trigger G in its normal position, and when thereciprocating headerB reaches its backward or retracted position a pin bthereon engaging the end of the lever or trigger G vibrates the same, soas to withdraw the lowermost pin g and permit the lowermost can head tofeed forward. When the header B moves forward to head the can, thespring causes the lever or trigger G to resume its normal position andthus permit the suc ceeding can head to move down into position againstthe lowermost pin 9'.

The headers B B are automatically reciprocated back and forth asrequired by a continuously revolving cam H on the main driving shaft K,which cam engages the pins, projections or friction rollers B Bconnected with the reciprocating headers B B. K is the drive wheel orpulley. Motion is communicated from the continuously revolving shaft Kto the continuously revolving shaft E of the can body feeder by means ofthe connecting gears 70 k k k 70 the first of which is on the shaft Kand the last of which is on the shaft E the intermediate gears being onthe intermediate shafts 70 W.
